Lhasa is a city and administrative capital of the Tibet Autonomous Region of the People's Republic of China. The main urban area of Lhasa is roughly equivalent to the administrative borders of Chengguan District, which is part of the wider Lhasa prefecture-level city, an area formerly administered as a prefecture.
Lhasa is the second most populous city on the Tibetan Plateau after Xining and, at an altitude of 3,490 metres (11,450 ft), Lhasa is one of the highest cities in the world. The city has been the religious and administrative capital of Tibet since the mid-17th century. It contains many culturally significant Tibetan Buddhist sites such as the Potala Palace, Jokhang Temple and Norbulingka Palaces.
